The pathogenicity of four isolates of three fungal species against females and cysts of Heterodera schachtii on water agar and the effects of fungal filtrates on motility of second-stage juveniles were examined. Rates of egg colonization by the fungi were measured after 3 weeks at 20 °C on 0.8% water agar. Fungi penetrated both females and cysts of which 60, 36, 21 and 17% of the eggs were infected by the two isolates of Paecilomyces lilacinus (PL 8.1 & PL 25.4), Cylindrocarpon destructans var. crassum and Chaetomiummurorum, respectively. Filtrates of the fungi reduced mobility of the nematode J2 after 24 and 48 h incubation periods. Isolate 8.1 of P. lilacinus paralyzed 100% of the J2 after both 24 and 48 h incubation periods. After 48 h of incubation the extracts of isolate 25.4 of P. lilacinus, C.destructans var. crassum and C.murorum paralyzed 25, 22 and 9% of the J2, respectively.
